Title: Window for transmitting high-frequency wave
Inventor: YAMAKAWA AKIRA
IPC: C04B35/58
Filed: 1988-07-12
Abstract: PURPOSE:To prevent the breaking of a window material due to thermal stress produced by high-frequency waves with high output by using AlN-based ceramics having a specified heat conductivity or above and superior high-frequency wave transmitting property. CONSTITUTION:This window for transmitting microwaves is made of AlN-based ceramics having >=50W/m.K heat conductivity. AlN ceramics contg. >=95vol.% AlN and having <=10 dielectric constant, <=0.001 dielectric loss and >=20kg/mm<2> bending strength is preferably used in the form of a dense sintered body having <5% porosity. In the case of a low AlN content, the heat conductivity of the ceramics is reduced and the window material is broken by heat generated by the absorption of microwaves. In the case of only AlN, it is difficult to obtain a dense sintered body and airtightness is not ensured, so a small amt. of a sintering aid is desirably added.

Title: Semiconductor device
Inventor: MIYAZAWA KAZUYUKI
IPC: H01L27/02
Filed: 1984-08-24
Abstract: PURPOSE:To release energy of external surge voltage to the outside of input protection circuit without destruction of elements by connecting the one of semiconductor regions to the input bonding pad and providing an input protection circuit connected to a constant potential to the other semiconductor region. CONSTITUTION:When an input contact part 7a breaks down, an external energy enters a semiconductor region 7 through the contact part 7a. In this region, voltage drop is lower at the area nearer to the contact part 7a and therefore a voltage difference between a semiconductor substrate 5 and region 7 becomes larger. Such breakdown voltage can be enhanced by surrounding such part with a well region 18. The region prevents breakdown of resistance 3 at the area nearer to the input contact part, namely breakdown of junction by concentration of current when breakdown occurs. For an external surge voltage exceeding a punchthrough voltage between the well regions 17, 18 of a bipolar transistor TR10, it is absorbed by a semiconductor egion 19 other than the input protection circuit 9. When its transistor 10 is conductive, a limitation resistance Rw limits the current so that unwanted excessive current does not flow.

Title: Method for generating ultrasonic wave signal
Inventor: KOSHIDA AKIRA
IPC: G01B17/00
Filed: 1980-12-13
Abstract: PURPOSE:To generate ultrasonic wave signals of large amplitudes and a uniform distribution directly in a metallic columnar body by flowing electric current instantaneously to the coil made of an insulated covered conductor wound on the outer side of said body. CONSTITUTION:A coil is formed by winding an insulated covered conductor on the outer side of a metallic columnar body of a cylinder or bar shape and electric current is flowed instantaneously to this coil. The metallic columnar body is deformed in a radial direction by the effect of the flux generated at that time, whereby ultrasonic wave signals are generated. For example, an insulated and covered conductor is wound on the outer side of a metallic columnar body 1 to form a coil 2. Both ends of such coil are connected via a switch 3 to a capacitor 4. On the other hand, an electric power source 5 is connected to a capacitor 4 via a rectifier 6 to charge the same. When electric current is flowed to the coil by closing the switch 3, the effect of the flux generated at that time forces the metallic columnar body to be deformed in a radial direction by magnetic force if it is a ferromagnetic material and by the effect of eddy current if it is a nonmagnetic material, thereby generating ultrasonic wave signals.
